Unified Power Measurement

Flukes patented Unified Power Measurement sys-tem (UPM) provides the most comprehensive viewof power available, measuring: Parameters of Classical Power (Steinmetz 1897)

and IEEE 1459-2000 Power Detailed Loss Analysis Unbalance AnalysisThese UPM calculations are used to quantifythe fiscal cost of energy loss caused by powerquality issues. The calculations are computed,along with other facility-specific information,by an Energy Loss Calculator that ultimatelydetermines how much money a facility losesdue to wasted energy.

Energy savingsTraditionally energy savings are achieved bymonitoring and targeting, or in other words, byfinding the major loads in a facility and optimiz-ing their operation. The cost of power qualitycould only be quantified in terms of downtimecaused by lost production and damage to electri-cal equipment. The Unified Power Measurement(UPM) method now goes beyond this to achieveenergy savings by discovering the energy wastecaused by power quality issues. Using theUnified Power Measurement, Flukes Energy LossCalculator (see screen shot below) will determinehow much money a facility is losing due to wasteenergy.

Unbalance

UPM gives a more comprehensive breakdown ofthe energy consumed in the plant. In addition tomeasuring reactive power (caused by poor powerfactor), UPM also measures the energy wastecaused by unbalance; the effect of unevenlyloading each phase in three-phase systems.Unbalance can often be corrected by reconnect-ing loads on different phases to ensure thecurrent drawn on each phase is as equal aspossible. Unbalance can also be corrected byinstalling an unbalance reactance device (orfilter), that will minimize the effects. Correctingunbalance should be basic good housekeepingin the facility as unbalance problems can causemotor failure or shorten equipment life expec-tancy. Unbalance also wastes energy. UsingUPM can minimize or eliminate that energywaste, thus saving money.

HarmonicsUPM also provides details of the energy wastedin your facility due to the presence of harmonics.Harmonics may be present in your facility due tothe loads you operate or may be caused by loadsin adjacent facilities. The presence of harmonicsin your facility can lead to: overheating transformers and conductors nuisance tripping of circuit breakers early failures of electrical equipmentQuantifying the cost of wasted energy due to thepresence of harmonics simplifies the return-on-investment calculation needed to justify purchas-ing harmonic filters. By installing a harmonicfilter the ill effects of harmonics can be reducedand energy waste eliminated, resulting in loweroperational costs and more reliable operation.

Unbalance The supply voltage unbalance is evaluated using the method of symmetrical components according to IEC61000-4-30Flicker According to IEC 61000-4-15 flickermeterfunctional and design specification.

Includes 230 V 50 Hz lamp and 120 V 60 Hz lamp models.Transient capture Captures waveform triggered on signal envelope. Additionally triggers on dips, swells, interruptions and Amps levelInrush current The inrush current begins when the Arms half cycle rises above the inrush threshold, and ends when the Arms half cycle

rms is equal to or below the inrush threshold minus a user-selected hysteresis value. The measurement is the square root ofthe mean of the squared Arms half cycle values measured during the inrush duration. Each half-cycle interval is contiguousand non-overlapping as recommended by IEC 61000-4-30. Markers indicate inrush duration. Cursors allow measurement ofpeak Arms half cycle.

Mains signaling Measurements are based on: either the corresponding 10/12-cycle rms value interharmonic bin or the rms of the four nearest10/12-cycle rms value interharmonic bins per IEC 61000-4-30. Limit setup for Monitor mode follows EN50160 standard limits.

Time synchronization Optional GPS430-II timesync module provides time uncertainty 20 ms or 16.7 ms for time tagging of events and timeaggregated measurements. When synchronization is not available, time tolerance is 1-s/24h
